Facebook COO Sheryl Sandberg admitted Friday that the Cambridge Analytica data breach came to Facebook's attention two and a half years ago, in December of 2015, but the company failed to take the same security steps they are now.

"We could've done this two and a half years ago," Sandberg admitted. "We thought the data had been deleted and we should have checked. They gave us assurances and it wasn't until other people told us it wasn't true ... We had legal assurances from them that they deleted it. What we didn't do is the next step of an audit and we're trying to do that now"
— Sheryl Sandberg during an interview on NBC's TODAY show with Savannah Guthrie

The average American's workweek has gotten 10% longer during the pandemic, according to a new Microsoft study published in Nature Human Behaviour.

Why it matters: These longer hours are a key part of the pandemic-induced crisis of burnout at U.S. firms — and workers are quitting in droves.

Airbnb CEO Brian Chesky to herald "travel revolution"

Airbnb CEO Brian Chesky will argue this week that the world is undergoing a "travel revolution," in which some parts of the industry stay shrunk but the sector ultimately comes back "bigger than ever."

Why it matters: Chesky, who faced the abyss when the world shut down last year, foresees a significant shift in how people move around, with more intentional gatherings of family, friends and colleagues — even if routine business travel is never what it once was.

Managing traffic in the skies is becoming a lot harder

Planes used to be the only aircraft crisscrossing the sky. Now there are drones, more frequent rocket ships and — soon — flying taxis, elbowing their way into the National Airspace System.

Why it matters: Managing the congestion up above is becoming an urgent mission for America's traffic cops in the sky. While the Federal Aviation Administration has a stellar safety record when it comes to commercial aviation, its challenge is infinitely more complex today.
